For the following equation, what would you do first? -8n+4(1-5n)=-6n-14

1-5n

Step-by-step explanation:

you would do 1-5n because its in brackets, the order of opperation is

Brakcets

Order (Power ofs)

Division and Mulitplication

then do addition and subtraction

when doing division and multiplication and subtraction and addition go left to right to find what part goes 1st.

Hope this helped!

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
